'Strengthen skills' - why 10XP every time?
When I started learning I used to get 3,5,7 XP points for one strengthening session. Then I had some 8 days break and continued learning and what happens now is 10XP points gain anytime I finish to Strengthen my skills. It shows 5/5 mastery on each unit and on the other side it shows overall 'Average Strength' when I look at the level of mastery on Android app.
Is it normal or kind of a bug maybe?
